North drums are horn shaped drums that were designed to project their sound outward, so the audience can hear the most direct qualities of the drum. Their inventor, Roger North, created the drums sometime around 1968, played them himself from 1970, obtained a patent, and then began selling them to others in 1972. These original North drums were made of fiberglass, by hand. Sometime around 1976 North agreed to let another company manufacture and market the drums - hopefully in larger numbers. Music Technology Incorporated (MTI) then began to produce the drums using an injection-molded resin process. The drums were made in Italy. They stopped selling the drums in the early 80's but there is an excellent used market for the drums, and a small though loyal contingent of North Drum players.
There is a big difference between the fiberglass shells and the injection-molded, MTI-produced shells. The sound is different, the bearing edges are different, and the overall build quality is different. MTI drums have a ‘Made In Italy’ sticker under one or more of the lugs, and generally have sticker badges. Fiberglass drums have metal plates for badges. In general the MTI drums have cleaner bearing edges and more consistent build quality - they were all molded in the same machines! The fiberglass drums were all hand made and each drum is different. The thickness fo the shells vary from kit to kit, and the shell thickness even varies from one side of the drum to another. Bearing edges on the fiberglass drums are inconsistent and coarse - however generally this has no impact on the sound. Speaking of the sound - North drums are loud, lots of attack, very little sustain - extremely percussive!
